Some really scary stuff is heading our way in the future, the first known variant of it has already been made and its scary as hell.
Three years ago, security consultant Dragos Ruiu was in his lab when he noticed something highly unusual: his MacBook Air, on which he had just installed a fresh copy of OS X, spontaneously updated the firmware that helps it boot. Stranger still, when Ruiu then tried to boot the machine off a CD ROM, it refused. He also found that the machine could delete data and undo configuration changes with no prompting. He didn't know it then, but that odd firmware update would become a high-stakes malware mystery that would consume most of his waking hours.
In the following months, Ruiu observed more odd phenomena that seemed straight out of a science-fiction thriller. A computer running the Open BSD operating system also began to modify its settings and delete its data without explanation or prompting. His network transmitted data specific to the Internet's next-generation IPv6 networking protocol, even from computers that were supposed to have IPv6 completely disabled. Strangest of all was the ability of infected machines to transmit small amounts of network data with other infected machines even when their power cords and Ethernet cables were unplugged and their Wi-Fi and Bluetooth cards were removed. Further investigation soon showed that the list of affected operating systems also included multiple variants of Windows and Linux.

Sounds like a Halloween joke?

An existing application of sound based transmission of information is voice activation. You speak and your computer/phone/gps does what you say. badBIOS uses that ability but on a much more basic level instead using inaudible sound.
Also, when you disconnect the power cable from a computer, it takes about 24 hours for the capacitors in the power supply to lose their charge. So technically speaking, the motherboard will still have a current and it can still be operating.
Questionable firmware isn't hard to accept and I am sure there's quite a bit of prior art there, but the transmission of data reliably directly after power loss is unlikely, and while totally disconnected? There is not going to be a way to maintain a network stack capable of this in any way so I don't understand why they would make the claim.....
